--------------------------------
Changes in version 1.7:
- new APNG decoder based on apngdis 2.8
--------------------------------
Usage (for command-line version):
apng2gif anim.png [anim.gif] [-t tlevel] [-b bcolor]
Options:
-t 128
will set the transparency threshold level as 128, so pixels
with alpha level less than 128 will become fully transparent.
-b 255 0 0
-b "#ff0000"
will set the background color as red, so partially transparent
pixels will be composed over red. When -b is used, -t is ignored.
When no options are specified, default threshold is 128,
no background color.
